This image displays the complete assembly, including the bronze top housing, clear plastic sight glass, and the internal white plastic strainer basket visible through the sight glass. The inlet and outlet ports are visible on the bronze housing.
Key Components:
- Bronze Head Assembly: The robust top section containing the inlet and outlet ports.
- Clear Sight Glass: A transparent plastic cylinder allowing visual inspection of the strainer basket and accumulated debris.
- Non-Metallic Plastic Strainer Basket: The removable internal filter element that captures debris.
- Drain Plug: Located at the bottom of the sight glass for easy draining and flushing.
- Mounting Brackets: Integrated into the bronze head for secure installation.
4. Setup and Installation
Proper installation is crucial for the performance and longevity of the raw water strainer. Follow these steps carefully.
4.1. Pre-Installation Check
- Verify all components are present and undamaged upon unboxing.
- Ensure the installation location provides adequate space for future maintenance, including removal of the sight glass and basket.
- Confirm the strainer's port size (2") matches your vessel's raw water system requirements.
4.2. Mounting Location and Orientation
- Select a sturdy, flat surface for mounting, preferably above the waterline to facilitate maintenance.
- Use appropriate marine-grade fasteners (not included) to secure the strainer's mounting brackets firmly to the chosen surface.
- Ensure the strainer is mounted vertically with the clear sight glass facing downwards. This orientation allows for proper debris collection and efficient drainage.
4.3. Plumbing Connections
- Connect the raw water intake line from the seacock to the inlet port of the strainer.
- Connect the outlet port of the strainer to the intake of your engine's raw water pump or other equipment.
- Use marine-grade hoses and double hose clamps on all connections to ensure a secure and watertight seal.
- Apply a suitable marine-grade thread sealant to any threaded connections as per the sealant manufacturer's recommendations.
- Avoid overtightening threaded plastic components.
5. Operating Instructions
The raw water strainer operates passively to filter debris from your vessel's raw water intake. Regular monitoring of the sight glass is essential for optimal performance.
5.1. Initial Start-up
- After installation and before starting your engine, slowly open the raw water seacock to allow water to fill the strainer.
- Visually inspect all connections for any signs of leaks.
- Ensure the clear sight glass is completely full of water and free of large air pockets. If air is present, briefly open the drain plug to purge air, then re-tighten.
5.2. Normal Operation
- The strainer continuously filters raw water as it flows through to your engine or other equipment.
- Periodically inspect the clear sight glass for accumulated debris. The frequency of inspection will depend on the water conditions in your operating area.
- A noticeable accumulation of debris or a reduction in water flow to your engine indicates that the strainer basket requires cleaning.
6. Maintenance
Regular maintenance ensures the efficiency and extends the lifespan of your raw water strainer. The non-metallic plastic basket is designed for easy cleaning.
6.1. Cleaning the Strainer Basket
- WARNING: Before performing any maintenance, always close the raw water seacock to prevent water ingress into the vessel.
- Place a bucket or suitable container beneath the strainer to catch any residual water and debris.
- Unscrew the drain plug at the bottom of the sight glass to drain the water and any loose debris.
- Carefully unscrew the clear sight glass from the bronze head.
- Gently remove the non-metallic plastic strainer basket from the sight glass.
- Rinse the basket thoroughly with fresh water to remove all accumulated debris. A soft brush or hose can be used for stubborn particles.
- Inspect the basket for any signs of damage, cracks, or deformation. Replace the basket if necessary.
- Inspect the O-ring seal on the sight glass for cracks, nicks, or signs of wear. Replace the O-ring if it appears compromised to ensure a watertight seal.
- Reinsert the clean basket into the sight glass, ensuring it is properly seated.
- Carefully screw the sight glass back onto the bronze head. Hand-tighten only to avoid damaging the plastic. Ensure the O-ring is properly seated and not pinched.
- Reinstall and hand-tighten the drain plug.
- Slowly open the raw water seacock and check for any leaks around the sight glass, drain plug, and plumbing connections.
6.2. Winterization
During winterization procedures, ensure the raw water strainer is completely drained of water to prevent freezing and potential damage to the sight glass or bronze head. It is recommended to remove the strainer basket and store it in a dry, protected area if the vessel is to be laid up for an extended period in freezing conditions.
7. Troubleshooting
This section provides solutions to common issues you might encounter with your raw water strainer.
| Problem | Possible Cause | Solution |
|---|---|---|
| Reduced Water Flow to Engine/Equipment | Clogged strainer basket with debris. | Clean the strainer basket thoroughly (refer to Section 6.1). |
| Reduced Water Flow to Engine/Equipment | Air trapped in the strainer or raw water lines. | Ensure the raw water seacock is fully open. Briefly open the drain plug on the strainer to purge air while water is flowing, then re-tighten. |
| Water Leakage from Strainer | Loose plumbing connections or hose clamps. | Inspect and tighten all hose clamps and threaded connections. |
| Water Leakage from Strainer | Damaged or improperly seated O-ring on the clear sight glass. | Remove the sight glass, inspect the O-ring for damage, clean it, ensure it is properly seated in its groove, or replace it if necessary. Reinstall the sight glass, hand-tightening only. |
| Water Leakage from Strainer | Cracked clear sight glass or bronze head. | Visually inspect the sight glass and bronze head for any physical damage. If cracked, the component or entire unit will need to be replaced. |
| Strainer Basket Difficult to Remove/Insert | Debris lodged around the basket or improper alignment. | Ensure all debris is cleared from the sight glass interior. Carefully align the basket during insertion. Do not force it. |
